  • Publication number: 20140326090
    Abstract: An electromechanical brake booster includes a hollow spindle and a hollow screw. Courses of thread are produced by deformation from metal and extrusion-coating them together with tubular supporting structures made of plastic. The hollow spindle and the hollow screw are produced as composite components.

  • Patent number: 7731304
    Abstract: The invention relates to an electronically regulatable vehicle brake system with traction control, in which a master cylinder is connected indirectly via a hydraulic unit to at least one wheel brake. The hydraulic unit has electromagnet valves and an externally triggerable pressure generator, for modulating the wheel brake pressure, optionally independently of the driver. For preventing wheel slip, the pressure generator is connected by its intake side to an intake conduit, among other things, that is controllable by an intake valve. To enhance the dynamics and improve the regulatability of a vehicle brake system, a self-aspirating pressure fluid storage unit is connected to the intake conduit and makes an aspiration volume available to the pressure generator.

  • Patent number: 5302930
    Abstract: An electromagnetic valve has a housing, a coil having a coil body and arranged in the housing, a pole element, a flux conducting element, a magnet armature cooperating with the coil body through the pole element and the flux conducting element. The flux conducting element is bracket shaped and arranged for position-accurate fixing and mounting of the coil, the coil body, and the pole element in the housing.
